Description

Table body with adjustable underframe Technical Field The utility model relates to the technical field of assembled tables, in particular to a table body with an adjustable bottom frame. Background The table body structure widely used in the market at present is mostly of a fixed design, namely, the connection relation between the table legs and the table plate can not be basically adjusted after the installation is finished, or limited operation can be carried out only in a mode of disassembling and assembling bolts. The structure has larger limitation in adapting to the assembly of table boards with different sizes or multifunctional scenes, and is not beneficial to users to flexibly assemble table bodies with more sizes according to actual demands. Based on the above, the utility model designs a table body with an adjustable bottom frame, so as to solve the above problems. Disclosure of Invention The utility model aims to provide a table body with an adjustable bottom frame, so as to solve the technical problems. The table body with the adjustable bottom frame comprises a first bottom frame, a second bottom frame and a table plate, wherein a joint pipe is inserted between the first bottom frame and the second bottom frame, a positive and negative screw rod is connected in a rotating mode in the joint pipe, screw rod sleeve blocks are connected to the outer walls of two opposite teeth of the positive and negative screw rod in a threaded mode, sliding ports are formed in the outer walls of the joint pipe corresponding to the two screw rod sleeve blocks, one ends, inserted into the first bottom frame, of the second bottom frame and the joint pipe, of the joint pipe are detachably connected with the two screw rod sleeve blocks respectively, a first bevel gear is fixed on the outer walls of the positive and negative screw rod, a hand-twisting rotary rod is arranged on the outer walls of the joint pipe in a rotating mode, a second bevel gear is fixed on one end of the hand-twisting rotary rod, and the first bevel gear is meshed with the second bevel gear. Preferably, two supporting legs are respectively arranged at the bottoms of the first bottom frame and the second bottom frame, and universal wheels with locks are fixedly arranged at one ends of the supporting legs of the first bottom frame and the second bottom frame. Preferably, a thread groove is formed in one end, facing the sliding port, of the screw rod sleeve block, a through hole is formed in the outer wall of the first bottom frame and the outer wall of the second bottom frame, corresponding to the thread groove, and the first bottom frame and the second bottom frame are locked with a fastening bolt through threads between the through hole and the thread groove. Preferably, one end of the second bottom frame is fixedly connected with an auxiliary pipe, and one end of the auxiliary pipe is spliced with the first bottom frame. Preferably, the table plate is detachably locked at the tops of the first bottom frame and the second bottom frame through bolts. Compared with the prior art, the utility model has the beneficial effects that: Firstly, through a bevel gear and screw rod linkage mechanism, the adjusting efficiency is improved, the stepless adjustment of the structural length of the bottom frame of the table body is realized, and the installation requirement of the table plates with multiple sizes is met; Secondly, can dismantle the desk plate structure promotes maintenance and change convenience, and overall structure removes nimble, stability is strong, is applicable to many occasions office and temporary assembly and uses.
